    The classic Q-Tron gets even funkier!

    Same design as the original EHX Q-Tron but with extremely useful Effects Loop and an Attack Response Switch. The Effects Loop gives the musician the ability to place an additional effect, or chain of effects between the EHX Q-Tron Plus's preamp and filter section without changing the envelope drive. This is particularly important with most distortion devices, as most all do not have much of an amplitude envelope.
    The FX loop will also fire up your creative juices to try all sorts of combinations in the effects loop: try the Micro POG into a Deluxe Memory Man. You can invent all sorts of novel effects. The added Response Switch selects between a slow, smooth, vowel-like attack and the fast, snaked response of the original Q-Tron.

    Mode Switch (LP, BP, HP, MIX)
    Determines what frequency range the filter will pass.

    Response Switch (Fast/Slow)
    Changes the sweep response between two optimized settings.

    Range Switch (HI/LO)
    Emphasizes vowel-like sounds in low position and overtones in high position.

    Peak Control
    Determines the resonance peak or Q of the filter.

    Gain Control
    In Boost mode, the Gain control functions as both a volume control and the filter sensitivity control.

    Boost Switch (Normal/Boost)
    Normal mode passes input signal through the filter at its original level. Boost mode increases the signal gain to the filter according to the Gain control setting.

    Sweep Switch (Up/Down)
    Selects the direction of the filter sweep.

    Bypass Switch (In/Out)
    Toggles between effect mode and bypass.

    FX Loop Return Jack
    From External musical effect output to Q-Tron+ filter process.

    Input Jack
    Musical instrument signal input.

    FX Loop Send Jack
    Musical instrument signal output to external musical effect.

    Effects Out Jack
    Output to amplifier.
